Be it known that We, Gnonen limitait BLAKE and @nannies EDWARD Simenon, subjects oit the King ot Great Britain and Ireland, and residingat, respectively, the Royal. Ash and 3l London Road, both in Bigg'leswade, Bedfordshire, lihigland7 have invented a new and useful Improvement in JointingI Composition, oit which the tollen/inga specification.

Our invention relates to a cinnposition tor application to the joints ot automobile engines and is praticularly intended to be applied to the gaskets used for making the joints between the cylinder head and cylinder block of internal coinlmstion engines and other similar joints. These gaskets which are frequently made up oit copper and asbestos, are often of a complicated torni and expensive to replace, and owing to the large area over Which the joints extend9 considerable difficulty is found in, making an effective joint tree from leakage,

Our intention comprises a composition adapted to be applied. to the surface ot such gaskes so as to make an effective joint bej tween the cylinder head and cylinder block or other parts. At the saine time the coinposition will enable the joint to be readily separated When desired Without damaging the gasket, which will come array quite easily vfrom the parte, and may be used again as frequently as desired.

According to this invention We employ a composition of soft soap and French chalk mixed together to the consistency of a paste. This composition is applied thinly over the Whole surface oit the gasket or the joint to Application filed. February 5, 1923.

be niade, and the parte are then placed. to-

gether and bolted up in the usual inanner.

The composition will render the joint eliective and leakprooi" and is particularly elicient in enabling a goed joint to be made between the cylinder head and cylinder block ot internal combustion engines `employing1 petrol or like volatile iuel.

rlhe soit soap and French chalk are mixed together in the proportion of approximately l0 parte off sott soap to one part oit French chalk by Weight. 'lhe paste so termed may be then placed in tins; or other suitable receptacles tor sale and is ready :tor immediate application to any joint to be made.

Instead oil? lirench chalk any other suitable powder or .fibrous material niay be added to the sott soap in a suitable proportion to torni a pas Je ot the required conAw sistency. Another suitable material 1to1 this purpose may comprise iine asbestos in a iowdered or fibrous state Asbestos is of a lieat resisting nature and Will torni a perinanent joint and assist in retaining` the soft soap in place in the interstices, between the and the top oit the cylinder head and cylinder' block, or other parts upon which it is used.
